Definitions

  • the present invention relates to a stator connection device for a rotating electrical machine according to the preamble of patent claim 1, to a stator according to patent claim 8 and to an electrical machine according to patent claim 10.
  • a switching device for a stator of an electrical machine is for example in DE 102016200115 A1 described by the applicant, which is used there to interconnect stator coils arranged in a circle on a stator core by means of winding bodies with coil ends.
  • the interconnection device has a plurality of connecting conductors which are arranged coaxially to one another and are electrically insulated from one another by means of insulating layers.
  • the connecting conductors are designed as ring disks and arranged in an axially staggered manner on the stator.
  • each connecting conductor has fastening sections designed as recesses, which are arranged axially overlapping one another and as a result of which the connecting conductors can be fixed together on one connecting element provided on a winding body of the stator and designed as a protruding pin.
  • the object of the present invention is to provide a space-saving, cost-effective and voltage-resistant interconnection device of the type mentioned initially, a stator and an electrical machine with such an interconnection device.
  • an interconnection device for a stator winding of a rotating electrical machine comprising a plurality of connecting conductors, which are designed as ring disks, are stacked coaxially and are electrically insulated from one another, each connecting conductor having a plurality of fastening openings distributed in the circumferential direction for fixing the interconnection device has a stator.
  • the connecting conductors are stacked in such a way that the fastening openings are positioned axially in relation to one another in sets and essentially overlap to form a common fastening passage.
  • the interconnection device is characterized in that the connecting conductors are spaced apart axially and are encapsulated in a plastic, as a result of which the interconnection device forms a metal-plastic composite part, in particular a plastic injection-molded part. At least two types of fastening openings with a different opening width are provided, which form a smaller and a larger fastening opening. A smaller and a larger fastening opening are formed in a fastening passage for two adjacent connecting conductors, with an annular space extending from a boundary of the larger fastening opening to a boundary of the smaller fastening opening being filled by the plastic.
  • the formation of the connecting conductors as ring disks, in particular from a strip-shaped or plate-shaped semi-finished copper product, enables an axially short interconnection device.
  • the connecting conductors of the switching device are therefore provided for an axially staggered arrangement on a stator, for which purpose the connecting conductors, each with a set of fastening openings, can be attached together to a fastening element provided on a stator and permanently fixed there.
  • the fastening openings mentioned are advantageously designed as circular recesses, for example punched-out portions with a different diameter.
  • the formation of fastening openings of different sizes on axially adjacent connecting conductors has the advantage that edge regions of these connecting conductors located at a circumferential position are further away than the axial distance, i.e. the axial interspace of these connecting conductors. As a result, an air and creepage distance of connecting conductors that are at a different electrical potential can be increased and the electrical dielectric strength can be increased.
  • the different fastening openings can preferably be formed alternately in the circumferential direction, so that a large fastening opening and a comparatively smaller fastening opening are adjacent in the circumferential direction.
  • the electrical breakdown strength in the area of the fastening openings is further increased by the introduction of the insulating plastic.
  • An injection-moldable thermoplastic or duroplastic material is advantageously used for encapsulating or overmoulding the interconnection device.
  • an elastomer can also be used, for example, depending on the application and installation space or environmental requirements.
  • the switching device is therefore available as a prefabricated structural unit for arrangement on a stator.
  • this can be manufactured as an off-tool assembly component with comparatively significantly reduced process and assembly steps.
  • the stator-side connecting conductor forms a contact surface in the area of a fastening opening for contact with a stator-side fastening area or fastening element.
  • a contact surface with the same cross section is therefore always available, regardless of the specific design of a fastening opening in the connection region, with all contact surfaces preferably also being designed in a common radial plane. Alternatively, the contact surfaces can also be designed in different planes, which, however, results in disadvantages in terms of production.
  • Partial filling of the larger fastening openings also has advantages on the end face of the interconnection device which is turned away from the stator.
  • a contact surface for a stator-side fastening element for example a fastening head, is formed there, which is independent of the respective circumferential position and the respective type of fastening opening and is therefore identical.
  • these contact surfaces can be arranged in the same plane, which offers advantages for automated production.
  • an axial passage with a constant internal width, in particular with a constant internal diameter can be produced by the explained introduction of the plastic over the axial extension of these connecting conductors.
  • a fastening element on the stator side can thus carry the interconnection device over its entire axial extension, as a result of which improved fastening is made possible.
  • the two types of fastening openings with different opening widths are provided on a connecting conductor.
  • the fastening openings are preferably arranged on a common pitch circle, with corresponding fastening elements on the stator also being formed on a pitch circle identical thereto.
  • the different types of attachment holes may be formed alternately in the circumferential direction.
  • the fastening openings on the connection device can be distributed over two partial circles with different diameters.
  • centering openings can be provided on the connecting conductors in order to accommodate the plurality of connecting conductors coaxially and spaced apart from one another in a tool, in particular for encapsulating with plastic in a casting tool.
  • the connecting conductors in such a way that the centering openings are positioned axially to one another in sets and essentially overlap to form a centering passage, with at least two types of centering openings with a different opening width being provided on each of the connecting conductors, which have a smaller and form a larger centering opening, the connecting conductors being stacked in such a way that a smaller and a larger centering opening are arranged axially adjacent in a set of centering openings and with an annular space extending from the boundary of the respective larger centering opening to at most almost to the boundary of the smaller centering opening, but does not include this immediate boundary with which the plastic is filled.
  • annular gap or an annular space remains on one of the connecting conductors within the annular space filled with plastic and the boundary of the smaller centering opening, which can accommodate a centering pin of the tool during injection molding or encapsulation of the structure and the centering pin in a surface area lying at least slightly outside the boundary of the smaller centering opening by means of a support surface, in particular can support a shoulder area.
  • two centering pins each from each of the two end faces of a connecting conductor, engage or engage in such a smaller centering opening.
  • the laterally spaced centering pins can reach through the other connecting conductors without touching them through the comparatively larger centering openings.
  • the centering openings with different diameters can be distributed on the connecting conductors such that at a given circumferential position of the interconnection device only one of the connecting conductors forms a centering opening with the smaller diameter.
  • connecting conductors in a tool can be arranged concentrically and at the same time axially spaced apart by circularly arranged centering pins with support surfaces formed at different levels, so that the insulating compound, ie the plastic, can penetrate into the axial and lateral spaces provided.
  • attachment openings described above can also be used for arranging and positioning the switching device in a tool, in that several centering pins with an outer diameter corresponding approximately to the inner diameter of the smaller attachment openings engage in them.
  • the connecting conductors favorably have coil connection areas for coil ends of a stator winding and power connection areas for the power supply of an electrical machine.
  • the coil connection areas can be designed as extensions protruding radially inwards or outwards, which are particularly advantageously arranged in a common radial plane and/or on a common circumferential area or pitch circle for interconnection with coil ends of a stator.
  • the coil connection areas can of course also be arranged in different planes.
  • spaced-apart recesses can be provided on the circumference of the axially staggered connecting conductors, through which respective coil connection regions of the further connecting conductors can be passed axially or can engage there.
  • automated production of the stator can easily be made possible by arranging the coil ends preferably in a common axial and radial position, with two coil ends adjacent on the circumference of two coils in each case being assigned to one and the same connecting conductor.
  • power connection areas can be provided on the stator, which, like the coil connection areas, are advantageously designed in one piece with the connecting conductors, and an extension that protrudes radially inwards or outwards is provided on them, which can be a connecting element such as for example, can accommodate a press nut.
  • the connecting conductors and the power connection areas can each also be formed in two parts.
  • a power connection area can advantageously be designed with a greater material strength or thickness compared to a base body of the connecting conductor.
  • a stator of an electrical machine is proposed, with an interconnection device having at least one of the features explained above being provided on it.
  • the stator can include a stator winding with a plurality of stator coils, the connection device being fixed to connecting elements of winding bodies of the stator coils.
  • the winding body can be made of a plastic, in particular an injection-mouldable plastic, so that corresponding connecting elements can easily be formed on it.
  • Retaining projections such as pins
  • attachment using clamps, snap-in elements or similar techniques is also possible.
  • a winding body can also have a winding area, which is formed by a winding carrier and two legs that delimit the winding area in the axial direction and are connected to the winding carrier.
  • the connecting element can be formed on a leg, on which the connecting conductors can be arranged axially or radially with respect to the winding area. Connecting elements can also be provided on both legs to securely fix the interconnection device on the stator.
  • an electrical machine with a rotor which includes a stator with at least one feature explained above.
  • FIG. 1 shows a schematic of an electrical machine 10, more precisely a permanently excited electrical synchronous machine of internal rotor design, with a rotor 14 that can be rotated about a rotor shaft 12 with an axis of rotation A and with a stator 16 that surrounds it radially on the outside
  • a laminated rotor lamination stack 20 is arranged on the outer peripheral surface, which carries a plurality of permanent magnets 22 spaced apart from one another on the circumference.
  • the stator 16 comprises an annular stator support 24, in the central recess of which is arranged an annular laminated core 26 of the stator, which is also formed from laminations.
  • the axis of rotation A thus also forms the central axis A of the stator 16.
  • the stator support 24 can represent an outer or an intermediate housing of the electrical machine 10, for example.
  • the stator laminated core 26 comprises an annular stator yoke 30 resting against the stator carrier 24 and teeth 32 projecting radially inwards from the latter, which teeth 32 are fitted with a plurality of stator coils 36 to form a stator winding. These stator coils 36 are wound around the teeth 32 with the aid of two insulating or winding bodies 40, 42 made of a heat-resistant plastic and are secured there against slipping.
  • the winding bodies 40, 42 each comprise a base region or winding support 40a that rests on the end face of the laminated core 26; 42a and two legs 40b, c; 42b, c, which delimit a winding area 43 in the radial direction.
  • the coils 36 are electrically assigned to individual strands, for which purpose the coil ends 36a, b are connected by means of an in 1 interconnection device 38, shown only schematically as a block, are interconnected in a predetermined manner.

  • the interconnection device 38 is fixed to the winding bodies 40 with the connecting conductors 52-56, as will be explained in detail and can be seen with reference to the further figures.
  • the switching device 38 is connected via power connection areas 52c, 54c, 56c of the connecting conductors 52-56 to power electronics 39a and control electronics 39b to an electrical energy source 39c ( 1 ), which can apply a current of variable phase and amplitude to the winding to operate the electrical machine 10 .
  • the connecting conductors 52-56 are made from a copper semi-finished product, in particular from a copper plate or a copper sheet, by means of a stamping process as ring disks.
  • the connecting conductors 52-56 are spaced apart axially and are encapsulated with a plastic forming a matrix 58, as a result of which the interconnection device is designed as a metal-plastic composite part, in particular as a plastic injection molded part.
  • the connecting conductors 52-56 are thus embedded in the plastic matrix 58, with only individual areas of the ring-shaped base bodies and coil connection areas 521, 541; 561 and power connection areas 52c, 54c, 56c are freely accessible.
  • the connection device 38 is arranged on the stator 16 coaxially to the central axis A with the axially staggered connecting conductors 52-56.

  • the interconnection of the coil ends 36a, b is shown to implement a delta circuit with three connecting conductors 52-56.

Recesses 52b, 54b, 56b are provided on a connecting conductor 52, 54, 56 in the areas extending in the circumferential direction between the coil connecting regions, through which the coil connecting regions 521-561 of the two further connecting conductors 52-56 are passed axially or can engage there . Examples are these recesses in the Fig. 2a-c marked.

  • a larger fastening opening 522a and a smaller fastening opening 542b are formed at a fastening passage 60 in two adjacent connecting conductors 52, 54. It can also be seen there that an annular space 62, which extends from a boundary of the larger fastening opening 522a to a boundary of the smaller fastening opening 542b, is also filled with the plastic 58.
  • This design means that the mutual distance between the borders of two axially adjacent fastening openings is increased and, due to the presence of the plastic 58, at the same time with one Dielectric filled, whereby a clearance and creepage distance and thus the dielectric strength between two lying at a different electrical potential connecting conductors is increased.

  • annular space 66 is thereby formed, which extends from the boundary of the respective larger centering opening 524a-526a up to a maximum almost to the boundary of the smaller centering opening 524b-526b, but does not enclose this immediate boundary.
